我有一个头文件,其中声明了一个void函数。在源文件中,我已经为此函数编写了实现。在编译项目时,我收到一个错误,表明我的实现与标题中的原型不匹配。
头文件(Dictionary.h)中的代码显示为:
void spellCheck(ifstream checkFile, string fileName, std::ostream &out);
源文件(Dictionary.cpp)中的代码显示为:
Dictionary::spellCheck(ifstream checkFile, string fileName, std::ostream &out){
_report.setFileName(fileName);
string end = "\n";
int words = 0;
int wrong = 0;
string word;
char currChar;
while(checkFile >> word){
currChar = checkFile.get();
while(currChar != "\\s" && currChar == "\\w"){
word += currChar;
currChar = checkFile.get();
}
out << word << end;
word.clear();
}
/*
_report.setWordsRead(words);
_report.setWordsWrong(wrong);
_report.printReport();
*/
}
这里有什么可能表明我试图返回一个整数值吗?
确切的错误是:
Dictionary.cpp:31:1: error: prototype for 'int Dictionary::spellCheck(std::ifstream, std::string, std::ostream&)' does not match any in class 'Dictionary'
Dictionary::spellCheck(ifstream checkFile, string fileName, std::ostream &out){
^
In file included from Dictionary.cpp:8:0:
Dictionary.h:21:10: error: candidate is: void Dictionary::spellCheck(std::ifstream, std::string, std::ostream&)
void spellCheck(ifstream checkFile, string fileName, std::ostream &out);
^
答案 0 :(得分:6)
您在这里错过Dictionary::spellCheck(ifstream checkFile, string fileName, std::ostream &out){
:
int
所以你隐式将函数定义为返回void Dictionary::spellCheck(ifstream checkFile, string fileName, std::ostream &out){
。
应该是:
System.currentTimeMillis
